What's the general consensus on "mothballing" circuits to use the amperage
elsewhere? I've got a 50A circuit for the range which is unused and am
trying to add a 40A circuit for refrigerated air. Just curious to see how
that is viewed. When it comes time to sell, is it a problem? Down the
road I suppose I'll try to upgrade to a real service (200A probably) but for
now and the near future, it's the 100A.

Is there no empty slot in the breaker box? Why can't you just add the
circuit and leave the range circuit alone, since it is unused?
Even if it were connected, it's not good to bake or roast when the AC
is on. You're adding heat to the house and then paying to remove it.
That's why outdoor grilling is so popular in the summer. Especially
before there was AC, cooking in the house in the summer made it even
(Do people remember these things?)
No available slots. After I sent this, it dawned on me that I could add
the A/C circuit to a subpanel I installed last summer specifically for my
220V tablesaw. I think I'd be pushing the feed into the subpanel if I
turned on the saw and the A/C comes on at the same time (both are 20A FLA
and the sub is 40A) but it'll work until I'm able to upgrade the service
altogether. Thanks much for the comments!
It's 8 ga, 40 A. The sub itself is rated to 60A I believe. I have 3
slots left. I intend on putting the 40A A/C breaker there as the other
breakers see very little use. I'll just have to shut off the A/C if I want
to run my tablesaw until I can afford to upgrade to 200A. I don't suppose
I can just change the innards in the main panel to make it a 200A can I? I
don't suppose I'd gain any spaces that way anyway.
Changing the panel does not change the feed. You can buy a larger panel,
use the 100A breaker for now, and have more slots. When you have the $$,
you can change the entry service and maybe the meter box and have 200A
You can also get an Amprobe and see just how much power you are using now to
see how fast you will have to upgrade.
I was hoping to not cut up the wall installing a larger can. I don't think
that's an option (buying different buses, etc....to fit the existing can to
bump up my rating). If I'm going to buy the larger panel anyway, I might
as well do it all. I've got a 200A meter, have to measure my feeds from
the meter to the main breaker, and confirm with the power company that their
feed is indeed ok for 200A. In the meantime, I'm gonna spend $24 on
breakers and get this A/C up. Then maybe this fall, I'll put in a real
service. Thanks much!
Thanks. After sending this, I realized I could in fact use my subpanel
that I installed last summer. There's a 220V/20A circuit there for my
table saw but otherwise, I can install the A/C there. Wish I'd thought of
that before I sent the message! So I can leave the range circuit alone.
I will plan to upgrade to a 200A service in the future however.
I am not sure that a 200 amp service would help you much, other than the box
will have more breaker positions, but that count is limited by code.
I have only a 100 amp service with a 24 breaker box. Years ago I outgrew the
tiny box size and added a subpanel to add breakers. I now have 3 subpanels
in my house and much more equipment than you indicate you have. While one
panel is a generator transfer panel, the others are just subpanels, and my
original main panel is mostly full of large breakers to feed the big loads
and subpanels. The subpanels take care of the smaller loads.
I have never had a problem with 100 amp being under capacity as far as power
draw, just I have a lot of lightly loaded breakers in my house and need all
the panels to hold them.
I'd like to go a similar route but unfortunately, there's really no place to
locate another subpanel where all the existing wiring would reach which
means I'd be ripping out walls and such. I think I can pull this off
within Code but I will have to move some breakers around. I've got a
serious imbalance on my phases as it is now (installed by the homebuilder no
